Beautifully maintained Antares with soft, sticky leather and front and back blocks. Excellent used condition! The L (medium width) seat measures a little shy of 16 1/2" and the standard flaps measure 13 1/4" long by 13 1/2" wide.
Dot to dot is 4 3/4" on an A/O tree (wide). This saddle is appropriate for the big shouldered, or round or barrel shaped horse or pony, with little to no wither, with a lower back as it has extra padding under the seat area. It is very generous fit in the shoulder and barrel area and will fit ponies and horses that usually only fit in an English, or hoop, tree.
You will not find a nicer saddle at this price point!
